Subject: usb: dwc3: gadget: clear DWC3_PENDING_REQUEST when request is queued
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=89185916d2295f7c4bc3a05adae25380b3e08e58;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

usb: dwc3: gadget: clear DWC3_PENDING_REQUEST when request is queued

Instead of clearing DWC3_PENDING_REQUEST when
we start transfer, let's do it when the request
is actually queued, that way we know for sure
that we're clearing in the right time.
